Attentional window and attentional capture 1 THE SIZE OF AN ATTENTIONAL WINDOW MODULATES ATTENTIONAL CAPTURE BY COLOR SINGLETONS
It has been proposed that during visual search a color singleton cannot capture attention in a bottom-up fashion (Jonides & Yantis, 1988). In the present study we manipulated the size of the attentional window by asking participants to detect either a global (diffuse attention) or a local shape (focused attention) before starting the search for a non-singleton target. We demonstrate that increa...
متن کاملAttentional capture modulates perceptual sensitivity.
The present study was designed to determine the spatial distribution of attention in displays in which an irrelevant color singleton was present. The results show that the presence of an irrelevant color singleton modulates target detectability (d'). The presence of an irrelevant singleton reduces the gain for input at the target location, particularly when the irrelevant color singleton was cl...

متن کاملThe Attentional Window Modulates Capture by Audiovisual Events
Visual search is markedly improved when a target color change is synchronized with a spatially non-informative auditory signal. This "pip and pop" effect is an automatic process as even a distractor captures attention when accompanied by a tone. Previous studies investigating visual attention have indicated that automatic capture is susceptible to the size of the attentional window. The present...
